OLD README

Attributes and Property Decorators for Unity that have access to the SerializedProperty used to draw the field. Thanks to [Marcel Wiessler](https://twitter.com/marcel_wiessler) and [this article from Sebastian Schöner](https://blog.s-schoener.com/2019-06-23-best-worst-code/) for the inspiration behind this implementation. ⚠️ This package requires 2020.3+ ⚠️ In versions below 2021, TypeProvider may draw incorrectly when combined with property drawers that nest the SerializedProperty. ## Attributes ### Type Provider - `[TypeProvider]` - `[TypeProvider(typeof(Example))]` Decorates a `[SerializeReference]` field, providing instances of a type that can easily be added via a dropdown. ![Type Provider Example](https://github.com/vertxxyz/Vertx.Decorators/raw/master/Documentation~/TypeProviderExample.gif) `TypeProvider` supports custom editors, property drawers, and decorators. It does this by injecting multiple modifications into the editor DLL. Other implementations may not achieve the same flexibility. ### DecoratorDrawerWithProperty An abstract DecoratorDrawer implementation that has access to the SerializedProperty used to draw the field. These decorators still do not draw on individual collection elements. If you have use case similar to `TypeProvider` that requires collection elements, please let me know. ## Installation
